The enhancement of plant resistance to pest infestation, improving plant growth parameters and productivity is in sustainable agriculture programs. Hydrogen peroxide (H₂O₂) is among the most effective compounds acts as a messenger molecule involved in acclimatory signaling and triggering tolerance against various biotic and abiotic stresses. In this study, three cultivars of common bean (Phaseolus vulgaris L.), Nebraska, Paulista, and Valentino were treated with H₂O₂ to evaluate some vegetative parameters, yield and the natural infestations Tetranychus urticae Koch. Leaf area scored the highest size in Valentino cultivar in (742.5 and 722.3 cm²) in response to 1.5 and 1 mM of H₂O₂ respectively compared to 416.3 cm² in the control. However, the Paulista cultivar reached the highest size 722.3 cm² in response to 1.5 mM H₂O₂ followed by 702.3 cm² in response to 1 mM H₂O₂ compared to 401.8 cm² in the control. Valentino cultivar scored the highest plant heights 81.8 cm in response to 1.5 mM H₂O₂ followed by 79.2 cm in response to 1 mM H₂O₂ compared to 43.2 cm in the untreated plants. Valentino cultivar scored the highest number of seeds, pods, and branches compared to the other two cultivars, while Nebraska scored the lowest number of seeds, pods, and branches in response to 1.5 mM hydrogen peroxide compared to control. Nebraska cultivar scored the lowest number of spider mites, T. urticae compared to the other two cultivars in response to 1.5 mM compared to control. An increase in ROS or hydrogen peroxide in the cells in response to exogenous application of hydrogen peroxide could be toxic to the T. urticae and affect its feeding and subsequently mite reproduction. Results from the existing investigation showed that exogenic application of hydrogen peroxide enhanced the resistance of common beans in response to T. urticae feeding.

在可持续农业计划中，增强植物对害虫侵害的抵抗力，改善植物生长参数和生产力。过氧化氢（H ₂ O ₂）是最有效的化合物之一，可作为信使分子参与适应性信号传导并触发对各种生物和非生物胁迫的耐受性。在这项研究中，用H ₂ O ₂处理了三个普通豆（菜豆，菜豆，保利斯塔和瓦伦蒂诺）三个品种，以评估其一些营养参数，产量和自然侵染Tetranychus urticae Koch的能力。叶面积在（742.5和722.3 cm ²）响应于1.5及H 1mM的₂ ö ₂分别比416.3厘米²在控制。然而，利斯塔品种达到最高大小722.3厘米²响应于1.5mM的ħ ₂ ö ₂接着702.3厘米²响应于1毫米高₂ ö ₂相比401.8厘米²在控制。华伦天奴品种对1.5 mM H ₂ O ₂的最高株高为81.8 cm，其次为对1 mM H ₂ O _2的79.2 cm。相比之下，未经处理的植物为43.2厘米。与其他两个品种相比，Valentino品种的种子，豆荚和树枝得分最高，而内布拉斯加州的1.5mM过氧化氢得分最低的种子，豆荚和树枝数量。内布拉斯加州品种得分最低数目叶螨，T.螨相比响应于1.5mM的其他两个品种与对照相比。响应于外源施加的过氧化氢，细胞中ROS或过氧化氢的增加可能对荨麻疹有毒并影响其摄食和随后的螨虫繁殖。现有研究的结果表明，外源施用过氧化氢可增强普通豆的抗逆性荨麻疹的喂养。
